Kubira Taishou is one of the Twelve Divine Generals. Among the twelve zodiac animals, he represents the boar. While having a rather rough-and-tumble personality, he's rather frank at the same time. People find it hard to refuse his requests, thanks to this. He's also got a tough, magnificent tail, and no matter what you do, you musn't say the word 'crocodile' in front of him. -- quote from Namu Amida Butsu! Wiki.
